HLXC AND REMOTE SYSTEM END-TO-END TEST PROCEDURES

Summary: This procedure provides instructions for performing end-to-end tests between a central office Version C, D, E, or G HLXC module and a remote Version E or Version D HLXR module. Performing an end-to-end test includes connecting the cross-connect jumper wires, verifying that the HDSL loops synchronize, and then sending a test signal between the two systems. This procedure assumes that installation of the HLXC modules, the remote module enclosure, and the remote HLXR module is complete. This procedure must be performed before attempting to operate the entire circuit or system that will be using this equipment.

Danger: To avoid electric shock, be careful when working near HDSL loop connections or telecommunications circuits. An electrical potential of ±130 volts exists on HDSL loop connections and telecommunications circuits. Coming in contact with this high electrical potential will result in death or severe personal injury.

Warning: To prevent electrical shock, never install telephone equipment in a wet location or during a lightning storm. When installing or modifying telephone lines, disconnect lines on the network side before working with uninsulated lines or terminals.

Caution: Electronic modules can be damaged by electrostatic discharge (ESD). Before handling modules, wear an anti-static discharge wrist strap to prevent damage to electronic components. Place modules in anti-static packing material when transporting or storing. When working on modules, always place them on an approved anti-static mat that is electrically grounded.

Note: Two technicians are required to perform this procedure, one at the central office and one at the remote location. Turn-up tests for the remote HLXR module should be done at the remote site following completion of stand-alone testing at the central office.

Do Items Below in The Order Listed

For Details Go To

1.Obtain the following tools and equipment:

•Anti-static wrist strap

•DS3 test set with DS1 option (for central office end of the circuit)

•DS1 test set (for remote end of the circuit)

•VT-100 compatible terminal or computer with terminal emulation software

2.Coordinate test with a technician located at the remote end of the circuit and ensure test procedures there have been completed.

3.Open the chassis front cover.
